New Airport Cooling Source Soars in Nashville

The Metropolitan Nashville Airport Authority's Nashville International Airport is now using a $10.4 million geothermal lake plate cooling system, the first for a U.S. airport. It pumps 50-degree F water from a former rock quary to the airport's plant facility, which cools the entire terminal.

According to Renewable Energy World, the the airport's chilled-water consumption has gone down 50% since the February 2016 switch to the new system. MNAA also expects to reduce electricity usage and potable water use.

MNAA received the 2016 Environmental Achievement Award in the Special/Innovative Projects Award category from the Airports Council International-North America for the geothermal lake plate project.
